This unofficial arcade hack is based on Metal Slug 3 and misleadingly presented as “Metal Slug 6.” It keeps the core SNK run-and-gun structure while altering sprites, enemy placement, and some gameplay behavior to create a different feel from the original release. Because it is not an official sequel, it is mainly remembered as a curiosity within arcade bootleg culture rather than a canonical series entry.

The game uses a 2D side-scrolling perspective where players advance through stages, shoot enemies with standard series weapons, throw grenades, and pilot Metal Slug vehicles. Its overall stage flow closely follows Metal Slug 3, but some enemy waves, visual assets, attack patterns, and character appearances are modified. Success depends on memorizing spawn points, reacting quickly to altered bullet patterns, using jump and crouch correctly, and managing weapon pickups through branches and boss fights.

Marco Rossi

One of the main heroes of the Metal Slug series and commonly retained as a playable character template in this type of hack.

Tarma Roving

A recurring series protagonist associated with vehicle combat and heavy firepower, usually preserved in bootleg character rosters.

Eri Kasamoto

A classic playable character from the series, often included in modified Metal Slug 3-based versions.

Fio Germi

A PF Squad member who typically remains selectable in hacks built on the Metal Slug 3 framework.

Since this version modifies Metal Slug 3, original-stage knowledge helps but does not guarantee safety. Focus on survival first and learn where changed enemies appear before chasing prisoners or score. Use crouching often against horizontal fire, save grenades for dense groups, and avoid overcommitting in vehicles when the screen becomes crowded. In boss fights, spend a cycle reading altered attack timing, identify safe zones near the screen edges, then commit to damage during openings.

Tips

Use Metal Slug 3 route knowledge as a base, but expect enemy placements to differ.

Tips

Shotgun and Thunder Shot are especially valuable for quick crowd control.

Tips

If a boss pattern looks unfamiliar, survive one cycle before trying to optimize damage.

User Reviews

Its novelty comes from seeing a familiar game remixed with changed visuals and encounter setups.

User Reviews

The core feel of Metal Slug 3 remains fun, though the balance is rougher than the official game.
